Facile synthesis of nanocrystalline β-SnWO 4 : as a photocatalyst, biosensor and anode for Li-ion battery

摘要: Here, we have successfully synthesised β-SnWO4 Nps via simple and low-cost co-precipitation method. XRD pattern confirms the wolframite cubic structure of which is belonging to P213 or T4 space group with an average crystallite size ~38 nm. FTIR spectrum shows bands at 620–825 cm−1 assigned characteristical stretching bending vibrational modes WO 6 , W–W bonds vibration W–O–W bridging in β-SnWO4. UV-DRS strong absorption band edge 604 nm estimated bandgap found be 1.9 eV. The excellent photocatalytic activity against indigo carminedye under various conditions Nps. In addition this, electrochemical senor performance toward quantification dopamine nanomolar concentration anode material for Li-ion batteries by showing high reversible discharge/charge capacity was explored.
